RULlNG-PEN.

SPECIFICATION forming part of Letters Patent No. 768,504, dated August 23,

Application filed December 4, 1903. Serial No. 183.728. (N0 model.)

To all whom it may concern:

Be it known that I, EUGENE A. BAGBY, a citizen of the United States, and a resident of Winchester, in the county of .Clark and State of Kentucky, have invented a new and Improved Ruling-Pen, of which the following is a full, clear, and exact description.

This invention relates to improvements in ruling-pens of the marking-Wheel type, and is particularly adapted for the use of bookkeepers, the object being to provide a ruling' drawings, forming a part of this, specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal section of a ruling-pen embodying my invention. Fig. 2 is a sectional view of the wheel-carrying and inking devices, and Fig. 8 is a perspective View of the ink-pad holder.

The pen comprises a body holder or handle 1, which is tubular and consists of any suitable materialsuch, for instance, as metal or hard rubber. W hile I have shown the body portion as cylindrical, it is to be understood that it may be rectangular or otherwise shaped without departing from the spirit of myinvention. Removably and reversibly placed in each end of the body is a wheel-holder comprising a hollow body portion 2' of a size to fit snugly in the body 1, and to limit its inward movement it is provided with an annular collar 3. It is also provided at one end with a removable cap or cover 4. The opposite end or extension 5 of the body 2 is considerably reduced in dimensions as compared withthe body 1, and this extension 5 has flat side walls, so that it may be guided evenly along the rulerthat is, prevented from turning while being moved along the rulerthus causing the marking-wheel 6, carried by the projection, to

make a clear and straight line. This marking-wheel 6 has a thin peripheral markingsurface, and it has its pinion-bearings in perforations formed in the opposite walls of the extension 5. walls project nearly to the lower periphery of the Wheel, so as to prevent ink from passing from the Wheel onto the ruler or onto a persons fingers. The wheel (indicated at 6) is constructed to form a single line.

The holder at the other end of the body 1 is provided with a Wheel 7, constructed to make a double line-that is, it has two peripheral marking-surfaces. The marking-wheel rec'eives its ink from a pad 8, consisting of any suitable absorbent material which will readily give up the ink, and this-pad is arranged in a holder consisting of a metal plate 9, bent to form two fingers or sections for engaging on opposite sides of the pad The ends of the holder members are tapered, as indicated at 10, and the walls of the extension 5 are correspondingly tapered, as indicated at theupper portion of Fig. 1. By this arrangement the holder will be heldrigidly in position, and also by tapering the holder and tapering said side walls to engage the tapers'of the holder the holder will be prevented from moving too far toward the wheel. The body portion of the holder has a width substantially equal to the diameter of the interior of the body 2, and at its inner end the holder is provided with a fingerpiece 11, by means of which it may be readily removed or inserted, and when the cap 4 is in place it will engage on the said finger-piece 8 5 and secure the holder rigidly in place. The members of the holder are slotted, as indicated at 12, so that a pin or other instrument may be inserted to adjust the pad when necessary.

The holder for the pad will preferably be of 9 spring yielding metal, so as to hold the pad firmly.

A ruling-pen embodying my invention will be found very convenient, because it can be readily carried in ones pocket, and by having different forms of ruling-wheels it may be quickly adjusted to use either one of the wheels.

While I have shown wheels for making single and double lines, it is obvious that wheels I00 It will be seen that these 55 may be employed for making other forms of lines, such as dotted lines, waved lines, or the like. It may also be stated that several wheelholders may be provided for use with one body portion or handle, so that different-colored inks may be used, as desired. When the device is not in use, the holders are to be so placed in the body portion 1 that the wheels are at the inner side of said body portion, and thus the pad will be protected from air that might evaporate the ink.

It is to be understood that a plurality of Wheels and wheel-holders may be furnished with the device and when not in use the wheels may be covered by suitable caps to prevent evaporation of ink, and, further, when rulingwheels with a rough surface are to be used, and which would tear the felt pad, it may be necessary to interpose between the Wheel and pad a middle wheel having a smooth periphery, the said middle wheel engaging with the pad through one of the slots in the pad-holder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A ruling-pen comprising a tubular body portion, a ruling-wheel holder removably and reversibly arranged in said body portion, the said holder having a reduced extension flattened at its opposite sides, a ruling-wheel mounted in said extension, and an ink-pad holder removably arranged in the wheel holder.

2. A ruling-pen comprising a tubular body portion forming a handle, a wheelholder comprising a tubular body adapted to be inserted in said handle, a reduced extension at one end of said wheel-holder having opposite flattened walls and opposite inclined walls, a ruling-wheel mounted in said extension, a pad-holder comprising two members having tapered edges to engage with said tapered walls of the extension, and a pad arranged in said pad-holder.

3. A ruling-pen comprising atubular body portion, a ruling-wheel holder comprising a hollow body portion, a removable cap therefor, the said wheel-holder having a reduced extension, a ruling-wheel mounted in said extension, a pad-holder consisting of a length of metal bent to form two members to engage opposite sides of the pad, a pad arranged between said members, and a linger-piece on said pad-holder adapted to be engaged by the cap on the wheel-holder.

4. A ruling-pen comprising a tubular body or handle, a hollow wheel-holder having a reduced extension having opposite inclined walls, a ruling-wheel mounted in said extension, a pad-holder eoi'nprising a length of yielding material bent to form two members for engaging opposite sides of a pad, the said members at the ends being tapered to engage with the said tapered walls, the members of said pad-holder being slotted, a pad arranged between said members, and a linger-piece on said pad-holder.

5. A ruling-pen comprising a tubular handle, wheel holding devices removably arranged in the opposite ends of said handle, wheels arranged in said wheel-holding devices, and ink -supplying pads arranged in the wheel-holding devices.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
